Identification of Epithelial-Mesenchymal Transition- (EMT-) Related LncRNA for Prognostic Prediction and Risk Stratification in Esophageal Squamous Cell Carcinoma

Figure 3

Univariate and multivariate COX regression analysis of EMT-related lncRNA in the training and validation cohorts. (a) The heatmaps displayed the hazard ratio (HR) and 95% confidence interval (CI) of EMT-related lncRNA with by univariate COX regression analysis in the training (a) and validation (c) cohorts. Blue to red in the color scale represented HR from low to high. HR.95 L: the low value in the 95% confidence interval of HR; HR.95H: the high value in the 95% confidence interval of HR. (b) The overlapping number of EMT-related lncRNA with (a) or (c) in the training and validation cohorts. (c) Multivariate COX regression analysis of EMT-related lncRNA. The contribution of EMT-related lncRNA to the overall survival (OS) of ESCC patients in the training cohort (upper panel). The time-dependent receiver operator characteristic (ROC) curves of the training (b) and validation (d) cohorts were used to evaluate the performance of the multivariate COX regression model.
